“ Halacha does not change, nor do the rest of yiddiin believe they are on some type of shlichus. These concept may seem mainstream to Chabad but not to mainstream yiddin. It’s a newer concept.”
Oh, please show me the Halacha lMoshe Misinai which discusses flicking lights on Shabbos?
Ie Halachic principles stay the same but Halacha definitely adapts to each situation, so there are changes in that way. Same with Chabad…
We’re all here on a shlichus from Hashem (I’m sure there are nigle sources for that, even Avodai heim etc)
And yes, there’sa plan with this world, which is to read it for Moshiach- and as every generation builds on previous generations work- the mission changes- for example in the time of the Tannaim and Amoraim- they were supposed to refine the chochma of the world- so that’s why every person wanted to be a philosopher. Look at today- it’s not the same world.
In general, The golus avoda was generally masculine- forcing kedusha upon the world / conquering it from klipa etc- so it was more desirable to be a boy.
Now we’re at the cusp of geula- we’re entering a feminine era where you will see Elokus radiating from the world upwards, the body will give life to the neshama etc etc (I’m sure theres nigle sources for everything, but these topics are more discussed in the Neshama of Torah- which Chassidus brings down to our level)
So now, for example, The Rebbe elevated women in a way they weren’t previously, to prepare for this era etc etc
Just some examples- but yes there’sa plan with Creation, and as the plan progresses, the focus of the time changes
